On Chebyshev Wells: Periods, Deformations, and Resurgence
Madhusudhan Raman, P. N. Bala Subramanian
We study the geometry and mechanics (both classical and quantum) of potential wells described by squares of Chebyshev polynomials. We show that in a small neighbourhood of the locu…
Exact WKB Analysis of Holomorphic Blocks
Sujay K. Ashok, P. N. Bala Subramanian, Aditya Bawane +3
We study holomorphic blocks in the three dimensional gauge theory that describes the model. We apply exact WKB methods to analyze the line operator…
A Hairy Box in Three Dimensions
Chethan Krishnan, Rohit Shekhar, P. N. Bala Subramanian
In this short note, we consider the phases of gravity coupled to a gauge field and charged scalar in 2+1 dimensions without a cosmological constant, but with box boundary co…
Applications of Holography
P N Bala Subramanian
This thesis consists of four parts. In the first part of the thesis, we investigate the phase structure of Einstein-Maxwell-Scalar system with a negative cosmological constant. We…
On the KKLT Goldstino
Chethan Krishnan, Himanshu Raj, P. N. Bala Subramanian
We construct general asymptotically Klebanov-Strassler solutions of a five dimensional truncation of IIB supergravity…
(Anti-)Symmetrizing Wave Functions
Chethan Krishnan, K. V. Pavan Kumar, P. N. Bala Subramanian
The construction of fully (anti-)symmetric states with many particles, when the single particle state carries multiple quantum numbers, is a problem that seems to have not been sys…
Robin Gravity
Chethan Krishnan, Shubham Maheshwari, P. N. Bala Subramanian
We write down a Robin boundary term for general relativity. The construction relies on the Neumann result of arXiv:1605.01603 in an essential way. This is unlike in mechanics and (…
Quantum Chaos and Holographic Tensor Models
Chethan Krishnan, Sambuddha Sanyal, P. N. Bala Subramanian
A class of tensor models were recently outlined as potentially calculable examples of holography: their perturbative large- behavior is similar to the Sachdev-Ye-Kitaev (SYK) mo…
A Dynamical Boundary for Anti-de Sitter Space
Chethan Krishnan, Avinash Raju, P. N. Bala Subramanian
We argue that a natural boundary condition for gravity in asymptotically AdS spaces is to hold the {\em renormalized} boundary stress tensor density fixed, instead of the boundary…
Hairy Black Holes in a Box
Pallab Basu, Chethan Krishnan, P. N. Bala Subramanian
We do a systematic study of the phases of gravity coupled to an electromagnetic field and charged scalar in flat space, with box boundary conditions. The scalar-less box has previo…
BRST Symmetry: Boundary Conditions and Edge States in QED
Nirmalendu Acharyya, A. P. Balachandran, Verónica Errasti Díez +2
In manifolds with spatial boundary, BRST formalism can be used to quantize gauge theories. We show that, in a gauge theory, only a subset of all the boundary conditions allo…
Phases of Global AdS Black Holes
Pallab Basu, Chethan Krishnan, P. N. Bala Subramanian
We study the phases of gravity coupled to a charged scalar and gauge field in an asymptotically Anti-de Sitter spacetime () in the grand canonical ensemble. For the conforma…
AdS (In)stability: Lessons From The Scalar Field
Pallab Basu, Chethan Krishnan, P. N. Bala Subramanian
We argued in arXiv:1408.0624 that the quartic scalar field in AdS has features that could be instructive for answering the gravitational stability question of AdS. Indeed, the cons…
